%description
|
|
This module implements the Rijndael cipher, which has just been selected as
|
|
the Advanced Encryption Standard.
|
|
|
|
* keysize
|
|
|
|
Returns the keysize, which is 32 (bytes). The Rijndael cipher actually
|
|
supports keylengths of 16, 24 or 32 bytes, but there is no way to
|
|
communicate this to 'Crypt::CBC'.
|
|
|
|
* blocksize
|
|
|
|
The blocksize for Rijndael is 16 bytes (128 bits), although the algorithm
|
|
actually supports any blocksize that is any multiple of our bytes. 128
|
|
bits, is however, the AES-specified block size, so this is all we
|
|
support.
|
|
|
|
* $cipher = Crypt::Rijndael->new( $key [, $mode] )
|
|
|
|
Create a new 'Crypt::Rijndael' cipher object with the given key (which
|
|
must be 128, 192 or 256 bits long). The additional '$mode' argument is
|
|
the encryption mode, either 'MODE_ECB' (electronic codebook mode, the
|
|
default), 'MODE_CBC' (cipher block chaining, the same that 'Crypt::CBC'
|
|
does), 'MODE_CFB' (128-bit cipher feedback), 'MODE_OFB' (128-bit output
|
|
feedback), or 'MODE_CTR' (counter mode).
|
|
|
|
ECB mode is very insecure (read a book on cryptography if you don't know
|
|
why!), so you should probably use CBC mode.
|
|
|
|
* $cipher->set_iv($iv)
|
|
|
|
This allows you to change the initial value vector used by the chaining
|
|
modes. It is not relevant for ECB mode.
|
|
|
|
* $cipher->encrypt($data)
|
|
|
|
Encrypt data. The size of '$data' must be a multiple of 'blocksize' (16
|
|
bytes), otherwise this function will croak. Apart from that, it can be of
|
|
(almost) any length.
|
|
|
|
* $cipher->decrypt($data)
|
|
|
|
Decrypts '$data'.
